1 RGB Digital Fibreoptic Sensors CZ-V20 Series Luster-cancel, small beam spot sensor head CZ-H7S Adjustable spot, colour detection sensor head Lustre-cancel, colour detection sensor head CZ-H5S Fluorescence detection UV sensor head CZ-H52 The Smartest RGB Sensor in the Industry Two new sensor head models have been added to the product line

2 The two new sensor heads will further expand the range of applications for the SUPER RGB sensor. Lustre-cancel, colour detection sensor head CZ-H5S Four types of sensor heads selectable according to target conditions and size. The lustre-cancel type cancels the influence of the lustre of a target. The adjustable spot type allows adjustment of the beam spot size according to the target. The fluorescence detection type can detect fluorescent materials. These sensor heads offer highly stable detection while solving conventional problems. Small beam spot type unaffected by lustre Lustre-cancel, small beam spot sensor head CZ-H7S Small beam spot of 1-mm diameter at an operating distance of 1 mm Shape, position, inclination, and surface lustre Less affected by changes in target condition World s first Extremely high power Utilises the world s first hybrid structure The SUPER RGB sensor was developed by a dramatic redesign of the sensor head structure to improve overall performance. The transmitter uses an optical fibre, which creates an incredibly uniform beam spot and helps reduce the size of the sensor head. The light-receiving circuit is built into the sensor head, enhancing its detection ability and improving stability.

3 Adjustable spot, colour detection sensor head Fluorescence detection UV sensor not affected by patterns or colours Fluorescence detection UV sensor head CZ-H52 Emits UV light to detect fluorescent materials and marks. Beam spot adjustable in sizes Versatile detection from a long distance UV light application Detecting fluorescent materials and marks First-in-its-class RGB light source for triple 1-bit calculation Three-colour light source for accurate target recognition The SUPER RGB sensor incorporates three separate colour LED s. The signal from each colour is converted into 1-bit data in the receiver to enable colour recognition. This ensures accurate detection regardless of target vibration. Simple sensitivity adjustment One-touch calibration The SUPER RGB sensor can be calibrated with the push of a button. This simple approach eliminates variation between operators and ensures continuous, stable detection.

4 Choose the sensor head that is right for your application CZ-H5S Lustre-cancel, reflective type CZ-H7S CZ-H5S Distance: 1 mm Beam spot diameter: ø1 mm CZ-H7S Small beam spot type The beam spot is as small as 1 mm in diameter at an operating distance of 1 mm. This ensures reliable detection of objects and components smaller than those detectable with conventional models. Distance vs. beam spot diameter (Typical) Distance 12 Beam spot diameter Less affected by shape, position, inclination, and surface lustre (Patent-pending) The CZ-H5S/CZ-H7S incorporates a polarizing filter which cancels the reflection from the glossy section and only recognises targets by their colour components. The CZ-H5S/CZ-H7S maintains accurate detection despite changing target conditions Units: mm 20 2 Distance: 40 mm Beam spot diameter: ø4.5 mm What is lustre? As the picture on the right shows, depending on the illumination some sections on a pepper s surface can appear white. Like human eyes, conventional sensors can not recognise the correct colours of such a target. Adjustable spot, reflective type Adjustable beam spot Three beam spot sizes can be easily selected by adjusting the slide switch, allowing a wide range of targets to be inspected. Medium Large Small ø5.5 (Large) ø4.5 (Medium) ø (Small) Long detecting range of 50 to 95 mm Detection is available within a range of 50 to 95 mm. The sensor can be mounted at a long distance and is less affected by changes in target position. Distance vs. beam spot diameter (Typical) Beam spot diameter (mm) Large Medium Small Distance (mm) 4

5 A wide variety of detection applications from every industry CZ-H7S CZ-H7S Detecting marks on bags printed with multiple colours The lustre-cancel type stably detects marks on bags even when the background of the mark vibrates or has lustre. The small beam spot ensures reliable detection of even small marks. Differentiation between the front and back sides of chips after being sealed in embossed tape The lustre-cancel type, which cancels the influence of specular reflection, stably differentiates between the front and back sides of chips even through a transparent film. Unacceptable Acceptable CZ-H5S CZ-H5S Detecting the presence/absence of grease By canceling the influence of surface lustre and target position, the CZ-V20 reliably detects grease, despite its non-uniform shape and position. Detecting the seam on a spray can Even when patterns are printed on spray cans, the sensor detects only the seam. Detecting a mark on a tube Selecting the small beam spot allows stable detection of small marks even from a long distance. Checking parts assembly The enhanced detection ability ensures stable detection of dark-coloured targets. Detecting improperly positioned labels Detection is stable because the colour recognition is not affected by the change in bottle colours. The interference prevention function assures successful detection when two sensor heads are mounted in close proximity. Detecting caps of different colours The CZ-V20 Series stably detects subtle colour differences that are difficult to detect with conventional sensors. Since detection is based on RGB components, it is less affected by target position or vibration. 5

6 High resolution amplifier for triple 1-bit calculation RGB light source for diversified target recognition The SUPER RGB sensor enables stable detection by using a three-colour light source. Advantage of the RGB light source 1 Accurate target recognition Single-colour light source Three-colour light source R G B R G B Almost no difference is recognized between certain colours, resulting in unstable detection. The received light is converted into a ratio of three colours, and the target is recognized by its colour. This ensures accurate detection. Advantage of the RGB light source 2 Less affected by changes in target position Single-colour light source Three-colour light source R G B R G B When the target position changes, the received light changes according to the distance between the target and the sensor head, resulting in unstable detection. Even when the target position changes and the received light changes, the ratio of the three colours does not change. Stable detection is ensured. Dual digital display & Direct access Both the current value and set value are displayed simultaneously. Sensitivity and fine adjustment can also be done manually.

7 Detections that were once difficult can easily and reliably be achieved. (Super I Mode) World s First Automatic selection of 7 different light combinations (Patent pending) In the Super I mode, the sensor detects the received light and automatically selects the most stable light from seven patterns. (There is no need for complicated settings because the light source is automatically selected during the sensitivity setting.)* * In reality, the colour of the emitted light does not change because the light combination is selected by the receiver. Red Green Blue Red + Blue Blue + Green Green + Red Red + Blue + Green SUPER mode + LEDs for exceptionally powerful detection SUPER 1X TURBO FINE 2X X LEDs Red, green, blue HSP (High speed) 1X level The combination of the SUPER mode + high-intensity LEDs has achieved unrivaled detection power. Even dark-coloured targets can be reliably inspected. Three detection modes for every target Super I C Detects the received light Detects the colour components C+I Detects the colour components and received light 7

8 Advanced features that provide 100% reliability Four independent outputs This function is useful for target differentiation. The sensor stores data of four types of targets simultaneously and allows the setting and output for each target independently. When the C or C+I mode is used, the bank function enables differentiation of up to eight different types of targets. C C+I Shift function This function is useful for detecting subtle colour difference. When there is a change in the surrounding environment over time, the displayed value can be compensated with the external shift input. (Patent pending) Shift input Super I Super I When the difference in sensitivity between the target and the background is small, providing shift inputs periodically will compensate for data variations. Automatic calibration adjustment C C+I After the sensitivity setting is complete, the set value can be finely adjusted by detecting actual acceptable or unacceptable targets and adding (increasing) or excluding (decreasing) the set value. (Patent pending) Attenuation function C C+I When the reflection from a target is too strong, the attenuation function can be used to decrease the sensitivity. Three types of timer functions C C+I Super I Super I Three types of timers are available: ON-delay, OFF-delay, and One-shot. The timer value can be set between 1 ms and 1,000 ms. External calibration function C C+I The sensitivity can be adjusted by using an external device such as a PLC.

9 Fluorescence detection UV sensor suitable for the detection of fluorescent materials and paints CZ-H52 Detection/operation indicators The detection and operation indicators show the current status of the detection. UV ON indicator Detection indicator Detecting fluorescent marks without being affected by patterns or colours The CZ-H52 emits UV light from the transmitter and detects the reflected light which was converted into visible light by the fluorescent material. Fluorescent materials and paints are normally invisible, however, they reflect visible light when UV light is applied. Targets which may contain fluorescent materials/paints Fluorescent label Fluorescent chalk Fluorescent lubricant Fluorescent dye Paper Adhesive Marking tool/ink-jet printer Fluorescent colour Label Sticker Optically bright materials Transparent film Marking ink Grease Ink and varnish/lacquer Felt-tip pen Printing ink And so on The CZ-H52 may be effective for detecting the above targets. Super-small head for space saving The small sensor head measures only (15 (W) x (H) x 24 (D) mm). It can be easily mounted in tight spaces. 24 mm Conventional model CZ-H52 Reduction to 1 10 mm 15 mm Applications Many targets contain fluorescent materials or paints. The fluorescence detection UV sensor may be able to detect targets which cannot be detected with photoelectric sensors. Try your target in an actual situation. Detecting labels on white containers The fluorescent component contained in a label is detected to check for the presence/absence of the label. Since the detection uses the fluorescent components, it can stably detect even white labels on white containers. Detection of presence/absence of instruction sheets (package insert) The CZ-H52 detects the fluorescent component contained in paper to check whether the instruction sheet (package insert) is properly inserted into each medicine package. Detection of presence/absence of invisible print The CZ-H52 detects the presence or absence of the print in invisible ink which contains a fluorescent component. The fluorescence detection UV sensor can stably detect print which cannot be detected with reflective type photoelectric sensors. Checking grease application on ball bearings The grease application is checked by detecting the presence/absence of the fluorescent component contained in it. Even glossy metal targets can be stably detected by ignoring the influence of specular reflection. 9
